Neurotransmitter 1 – Serotonin
One example of a neurotransmitter is serotonin, which is commonly associated with depression and aggression.
Serotonin is a body regulator it controls bodily processes such as sleep, libido and body temperature.
It protects us from negative emotions such as anxiety and depression.
Secreted into the human body by the pineal glands.
Low levels of serotonin due to efficient re-uptake in the pre-synaptic neuron leads to low levels of arousal and lack of positive emotion, hence symptoms of depression.
